Currently, the GRUB payload for coreboot does not detect the Western
Digital hard disk WDC WD20EARS-60M AB51 connected to the ASRock E350M1,
as that takes over ten seconds to spin up.

disk/ahci.c:621: cleaning up failed devs
```
GRUB detects the drive, when either unloading the module *ahci*, and
then loading it again, or when doing a warm reset.
As the ten second time-out is too short, increase it to 32 seconds,
used by SeaBIOS. which detects the drive successfully.
The AHCI driver in libpayload uses 30 seconds, and that time-out was
added in commit 354066e1 (libpayload: ahci: Increase timeout for
signature reading) with the description below.
> We can't read the drives signature before it's ready, i.e. spun up.
> So set the timeout to the standard 30s. Also put a notice on the
> console, so the user knows why the signature reading failed.

Rename grub_gpt_part_type to grub_gpt_part_guid and update grub_gpt_partentry
to use this type for both the partition type GUID string and the partition GUID
string entries. This change ensures that the two GUID fields are handled more
consistently and helps to simplify the changes needed to add Linux partition
GUID support.

Check the error bits in the interrupt status register. According to the
AHCI 1.2 spec, "Interrupt sources that are disabled (‘0’) are still
reflected in the status registers.", so this should work even though
grub uses polling
This fixes the following problem on a Fujitsu E744 laptop:
Sometimes there is a very long delay (up to several minutes) when
booting from hard disk. It seems accessing the DVD drive (which has no
disk inserted) sometimes fails with some errors, which leads to each
access being stalled until the 20s timeout triggers. This seems to
happen when grub is trying to read filesystem/partition data.
The problem is that the command_issue bit that is checked in the loop is
only reset if the "HBA receives a FIS which clears the BSY, DRQ, and ERR
bits for the command", but the ERR bit is never cleared. Therefore
command_issue is never reset and grub waits for the timeout.
The relevant bit in our case is the Task File Error Status (TFES), which
is equivalent to the ERR bit 0 in tfd. But this patch also checks
the other error bits except for the "Interface non-fatal error status"
bit.

In util/getroot and efidisk slightly modify exitsing comment to mostly
retain it but still make GCC7 compliant with respect to fall through
annotation.
In grub-core/lib/xzembed/xz_dec_lzma2.c it adds same comments as
upstream.
In grub-core/tests/setjmp_tets.c declare functions as "noreturn" to
suppress GCC7 warning.
In grub-core/gnulib/regexec.c use new __attribute__, because existing
annotation is not recognized by GCC7 parser (which requires that comment
immediately precedes case statement).
Otherwise add FALLTHROUGH comment.

iPXE adds Simple File System Protocol to loaded image handle, as side
effect it also adds Block IO protocol (according to comments, to work
around some bugs in EDK2). GRUB assumes that every device with Block IO
is disk and skips network initialization entirely. But iPXE Block IO
implementation is just a stub which always fails for every operation
so cannot be used. Attempt to detect and skip such devices.
We are using media ID which iPXE sets to "iPXE" and block IO size in
hope that no real device would announce 1B block ...
Closes: 50518
Returned from the OpenProtocol operation, the grub_efi_block_io_media
structure contains the io_align field, specifying the minimum alignment
required for buffers used in any data transfers with the device.
Make grub_efidisk_readwrite() allocate a temporary buffer, aligned to
this boundary, if the buffer passed to it does not already meet the
requirements.
Also sanity check the io_align field in grub_efidisk_open() for
power-of-two-ness and bail if invalid.
Map EFI_NO_MEDIA to GRUB_ERR_OUT_OF_RANGE that is ignored by diskfilter. This
actually matches pretty close (we obviously attempt to read outside of media)
and avoids adding more error codes.
This affects only internally initiated scans. If read/write from removable is
explicitly requested, we still return an error and text explanation is more
clear for user than generic error.

Store partition offset in cryptomount descriptor to distinguish between them.
Currently, some messages cannot be mapped to the port they belong to as
the port number is missing from the output. So add `port: n` to the
debug messages.

All current ciphers have blocks which are power of 2 and it's
unlikely to change. Other block length would be tricky to handle anyway.
This restriction allows avoiding extra divisions.
Avoid micro-optimization in grub_diskfilter_make_raid and make sure
name and fullname are independent strings. This avoids need to special
case it everywhere else.
Also fix memory leak in failure case in grub_diskfilter_make_raid.

Commit 750f4bacd3 put LV validation before
actual vg assignment. Make grub_diskfilter_make_raid to assign ->vg as
happens in other cases for consistency. Also clean up redundant code and add
explicit NULL lv->vg check in validate_lv.
Also fix segment validation in validate_lv; it became obvious when crash
was fixed.

Commit 588744d0dc caused grub-mkconfig
no longer to be forgiving of trailing spaces on grub-probe output
lines, which among other things means that util/grub.d/10_linux.in
no longer detects LVM. To fix this, make grub-probe's output
delimiting more consistent. As a bonus, this improves the coverage
of the -0 option.
